JORDAN HAMM, OF MAY, TEXAS.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 386,466, dated July 24,1888. Application filed November 1, 1887. Serial No. 253,991. (Nomodel.)

To all whom it may concern:

Be it known that I, JORDAN I-IAMM, a citizen of the United States,residing at May, in the county of Brown and State of Texas, haveinvented a new and useful Improvcmentin \Vindmills, of which thefollowing is a specification.

My invention relates to an improvement in windmills; and it consists inthe peculiar construction and combination of devices, that will be morefully set forth hereinafter, and particularly pointed out in the claim.

In the drawings, Figure l is a side elevation of a windmill embodying myimprovements. Fig. 2 is a longitudinal section on line i y of Fig. Fig.3 is a horizontal section taken on the line :0 00 ofFig. 1. Fig. 4 is atop plan view.

A represents a vertical rectangular frame, which is provided at asuitable distance from its lower end, in the center, with a bridge, B,on the central portion of which, on its upper side, is located an archedbracket, 0. Across the upper side of the frame A extends a pair oftransverse bars, 1), which are connected at their centers and in avertical line with the bridge by a block, ID. In the center of thisblock isjournaled a short vertical shaft, F, to the upper end of whichis attached a vane,G.

H represents a vertical shaft, the lower end of which isjournaled in thebracket 0, and is stepped in a hearing, I, arranged on the upper side ofthe center of the bridge B, the upper end of the said shaft- Hbeingjournaled in a vertical opening made in the lower end of the shaftF, and thereby the said shafts F and H are independently revoluble.

K represents a vertical cylindrical case,having the heads L, which areconnected together on one side for a suitable space by a curved plate,M, which is preferably made of sheet metal and extends around aboutone-third the circumference of the case. If desired, a piece of canvasof suitable size may be substituted for the metallic plate M. The upperside of the case is pivotally connected to the lower end of the shaft F,and the lower side of the case is journaled centrally on the shaft H andbears upon the upper side of the bracket 0.

N represents the wind-wheel, which comprises the circular horizontalheads 0, connected together by means of concave wings P, which arepreferably made of sheet metal, and

are curved, as shown in Fig. 3, and have their sides bent aroundbolt-rods It, which connect the circular heads of the wind-wheel. Theshaft H extends through the central portions of the heads of thewind-wheel and is firmly secured to the same, so that the wind-wheelrotates with the said shaft.

S represents a lever, which is attached to the lower portion of theshaft F just above the casing, and extends outwardly from the said shaftfor a suitable distance. To this lever is attached a depending rod, T,that extends to within a suitable distance of the ground.

Near the lower end of the shaft H is at tached a band-pulley, U, bymeans of which power may be transmitted from the said shaft to anysuitable machinery.

The operation of my invention is as follows: IVhen the lever Sisreleased, the shaft F and easing are disconnected and the casing cutsoff the wind from the wheel, as will be readily understood; but when thelever S, which is attached to the lower end of the shaft F, is made toengage with one of the notches T" in the head L of the case, (by meansof the depending rod T,) the shaft F and easing are attached to eachother and are free to rotate together, so that the vane G turns the saidshaft and casing to expose one side of the wind-wheel to the wind, andthus permit the wind to strike fairly upon the wings of the wind-wheelone side thereof, so as to rotate the wind-wheel and the shaft H.

Having thus described my claim- The combination of the horizontalwindwhcel, the semi-cylindrical case partly inclosing the same andindependently revoluble,the case having the notches T in its upper side,the vane having the shaft or port whose lower end forms the upper pivotfor the said case, and the lever S, having its inner end last to thevane shaft or port, and adapted to engage the said notches, and therebycause the case to expose any desired area of the wheel to the wind,substantially as described.

In testimony that I claim the foregoin g as my own I have hereto affixedmy signature in presence of two witnesses.

invention, I
